Peak-Flow Frequency Analysis for Selected Montana Streamgages
Science Center Objects
The Montana Department of Resources and Conservation requires peak-flow information for Federal Emergency Management Agency (FEMA) floodplain mapping for various locations across Montana. Accordingly, the USGS WY-MT Water Science Center has updated peak-flow frequencies for selected streamgages in the Beaverhead River, Clark Fork, Ruby, Jefferson and Madison River Basins, and for selected streamgages in Jefferson, Missoula, Granite, and Carbon Counties, Montana.
The data for these streamgages are publicly available on WY-MT WSC Peak-flow Frequency Analyses landing page.
The WY-MT WSC is currently analyzing peak-flow frequencies for selected streamgages in the Milk River Basin and in Teton and Powell Counties.

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabil
